Wanamaker, who last played for Fenerbahce, is 6'4" and 28 years old. He averaged 13.4 points, 4.1 assists, and 1.4 steals per game over the last 3 years in the EuroLeague. In addition, he was voted 2nd team All-EuroLeague in 2017-2018.

This move by the Celtics likely indicates that they will no longer have the need for back up point guard Shane Larkin, who was a solid contributor off the bench, but injured his shoulder during the 2018 playoffs after colliding with Joel Embiid.
